Valley power storage and air energy heat pump

Can Valley power phase change heat storage be used in commercial buildings?

The heating tests in commercial buildings show 53% savings in operating costs. The valley power PCHS heating technology shows good application prospects. The application of valley power phase change heat storage (PCHS) in commercial building heating has practical significance for the city's sustainable development.

Does a solar-assisted heat pump have phase change energy storage?

This paper introduces a novel solar-assisted heat pump system with phase change energy storage and describes the methodology used to analyze the performance of the proposed system. A mathematical model was established for the key parts of the system including solar evaporator, condenser, phase change energy storage tank, and compressor.

What is solar assisted heat pump heating system with phase change material (SC-ASHP-PCM)?

In this study, a solar assisted heat pump heating system with phase change material (SC-ASHP-PCM) system was constructed, and the single variation impact analysis and multi-factors optimization were carried out to balance the annual life cycle cost and building thermal comfort. The main results were drawn as follows:

How can a valley power PCHS system predict the energy storage duration?

Therefore, in the application of the system, it is possible to predict the energy storage duration and the amount of heat storage of the valley power PCHS system based on the building energy consumption data and the outdoor ambient temperature parameters of the heating seasons over the years.

What are the advantages of Valley power PCHS system?

As a result, based on the operation data and economic analysis of the commercial building, it can be seen that the valley power PCHS system applied to the winter heating of commercial buildings has the advantages of high energy storage density, stable energy storage temperature, flexible operation, modular installation and regulation.

Does a solar-air heat pump heating system with PCM thermal storage save energy?

A solar-air heat pump heating system with PCM thermal storage was constructed. The single variation impact analysis and multi-factors optimization were conducted. Formed an optimization objective function for energy-saving and non-guaranteed hour. The objective function decreased by up to 24.1% compared to the baseline situation.
